Is Betelgeuse, one of the sky’s brightest stars, on the brink of a supernova? And if you’d really like a clear view of the colors, try taking a 15- or 20-second exposure of Orion with tripod-mounted camera. (ESA/Herschel/PACS/L. At this time of year, in January and February, finding Orion is easy. The bright, ruddy star Betelgeuse (left) is part of this famous stellar pattern. We planned a long pack trip, and the question arose which of the ranch horses was strong enough to carry me through a long mountain trip (6 feet 3 inches and 220 pounds - my height and weight, not the horse’s). Betelgeuse: A red supergiant star, Orion’s second brightest star and the eighth brightest star in the night sky. You’ll notice that it has an orangey color. “ What is the name of that horse?” I asked. Once you’re aware of the red giant’s color and go looking for it, you should be able to clearly perceive its rusty hue in comparison to other nearby stars. One day, the orangey-red supergiant star Betelgeuse at the armpit of Orion, the Hunter—about 650 light years from Earth—will explode as a spectacular supernova. We might have to get up early, or stay out late, to see it at other times of the year, but if the super-rare event occurs in June, July or August when the sun appears to shine from close to Orion, then it won’t be much of a spectacle at all. Betelgeuse is an excellent example of this — in just 100,000 years, it will leave its home in the Orion constellation. That depends on when it occurs because Orion is a seasonal constellation. On a dark night, when the moon has dropped out of the evening sky at the end of the first week of January 2018, you might want to look at the magnificent Orion Nebula, or M42, the fuzzy patch in Orion’s Sword. Betelgeuse is moving so fast that the interaction between its stellar wind and the surrounding interstellar medium creates an immense bow shock 3 to 4 light-years wide. I'm an experienced science, technology and travel journalist and stargazer writing about exploring the night sky, solar and lunar eclipses, moon-gazing, astro-travel. Ultimately, the Gaia satellite’s exquisite parallax measurements may help decide the distance debate. Meet Barnard’s Star, Our Red Dwarf Neighbor, Meet Regulus, Little King of the Ecliptic. Of course, Betelgeuse is at such a distance that it may have already happened; as it is 642 light years from us, it could have exploded 642 years ago. “But why Battle Goose?” “Don’t know, sir, but he always was called that.”», By: Daniel Johnson As a red supergiant nearing the final phases of its life cycle, Betelgeuse has an estimated diameter around a thousand times that of the Sun, with an estimated absolute luminosity of 100,000 times the Sun. Betelgeuse also features in Aboriginal Australian mythology, as passed down through oral tradition. By . If Rigel were as close as Sirius, the brightest star visible to the eye (and only about 8.6 light-years away), Rigel would shine much more brilliantly than Venus, our sky’s brightest planet. «The author cannot help relating here an amusing story - changing, for the purpose, to the first person. Its name is derived from the Arabic for "hand of Orion." Bottom line: Many constellations have a bright star, but Orion has two: Rigel and Betelgeuse. Betelgeuse, also called Alpha Orionis, second brightest star in the constellation Orion, marking the eastern shoulder of the hunter.Its name is derived from the Arabic word bat al-jawzāʾ, which means “the giant’s shoulder.”Betelgeuse is one of the most luminous stars in the night sky. Betelgeuse is one of three stars in an asterism known as the “Winter Triangle.” The other two are Procyon in Canis Minor and Sirius in Canis Major. It’s most easily visible to everyone on the planet from December through May. Betelgeuse is the star at the shoulder of Orion, the iconic constellation in the shape of a hunter wielding a bow in the night sky. © 2020 Forbes Media LLC. Or it could happen in 100,000 years. A quick way to find Betelgeuse using Orion's Belt and Rigel. Copyright ©2020 AAS Sky Publishing LLC. Finding the brilliant red giant is an easy task, thanks to its prime location in a prominent constellation. Rigel, a blue-white supergiant, and Betelgeuse, a red supergiant, are the brightest stars in Orion.Thousands of newly formed stars can be found in the direction of the Orion Constellation. How do you pronounce Betelgeuse? How to See Betelgeuse. He's a longtime member of NASA's Solar System Ambassadors program. Betelgeuse – the other bright star in Orion – represents the Hunter’s right shoulder. Betelgeuse is in the upper left-hand corner of Orion when viewed from an “upright” perspective. Many constellations have a bright star, but Orion has two: Rigel and Betelgeuse. In the Northern Hemisphere, Orion begins to rise early in the evenings in December, and continues to dominate the southern winter sky until about April, when it begins to fade into the sunset. The pack trip turned out to be very successful, and my Betelgeuse carried me faithfully each day from dawn to dusk. It could happen tonight. Its distance is measured by its parallax, which the Hipparcos satellite measured as 6.55 milliarcseconds (which would give a distance of 500 light-years). Red Betelgeuse, also known as Alpha Orionis, is the 9th-brightest star in the night sky and 2nd-brightest in the constellation of Orion. September 3, 2020, By: Daniel Johnson You can find it by getting to know all the stars in the Orion, or by locating Orion’s Belt, which will be almost vertical in the night sky as its gets dark. Stars are in constant motion. The truth is, no-one knows, though Betelgeuse is known to vary in brightness because its atmosphere sheds a lot of dust. Decin et al.) But the star itself spans 45 milliarcseconds on the sky — as you can imagine, that complicates measurements of its motions on the sky. Its immense size makes its distance uncertain, though, which makes calculations of other properties (such as its mass) uncertain too. Tonight … look for Orion the Hunter, one of the easiest constellations to identify in the night sky. Recently, the star has visibly dimmed. (The bow shock is visible at infrared wavelengths, so don’t expect to see it through your scope!). Larry Sessions has written many favorite posts in EarthSky's Tonight area. His articles have appeared in numerous publications including Space.com, Sky & Telescope, Astronomy and Rolling Stone. To the ancient Egyptians, the constellation was Osiris, a god and primeval king in the culture’s mythology. You can’t miss these two brilliant beauties if you look eastward around 7 to 8 p.m. (your local time). By: Daniel Johnson It’s almost an exact equilateral triangle. Rigel and Betelgeuse reside on opposite sides of Orion’s Belt – three medium-bright stars in a short, straight row. “Battle Goose, sir,” answered the stable boy. You’ll also easily recognize Orion by its “Belt” stars, three medium-bright stars in a short, straight row. Location of Betelgeuse. Betelgeuse is a star in a hurry — travelling through space at about 67,000 mph (30 km/s) relative to the surrounding interstellar medium. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator.
